Narrative

Report for LER 50-366/1981-054 On 6-13-81, while operating at 91% power 2P33-P001B, drywell and torus H -02 analyzer recorder was found to be inoper-2 ative.

Tech Specs section 3.3.6.4-i requires both channels to be operative during power operation.

The plant was placed in a 30-day LCO.

This is a repetitive event as last reported on LER 50-365/1981-033.

The

cause

of this ev e.nt has been attributed to analyzer drift.

The analyzer, 2P33-P001B, was recalibrated per Comsip Delphi K-IV Hydrogen and Oxygen Analyzer procedure, HNP 3882.

The analyzer was declared operable and returned to service.

Plant operation was not affected as a result of this event.

The health and safety of the public was not affected.

A generic ceview revealed no inherent drift problems.

Unit 1 does not v.tilize this type of analyzer.
